The main difference between Parkinson’s syndrome and Parkinson’s disease is that Parkinson’s syndrome is often secondary to some other neurological diseases or the effects of toxins or drugs, so sometimes Parkinson’s syndrome is also called (secondary Parkinson’s disease). Clinically, Parkinson’s syndrome has the same manifestations as Parkinson’s disease, such as bradykinesia, dull expression, increased muscle tone, resting tremor, etc., but also has manifestations left over from the original disease, such as epilepsy, hemiparesis, headache, ataxia, eye movement disorder, slurred speech, postural hypotension, dementia, etc. The treatment of Parkinson’s syndrome is similar to that of Parkinson’s disease, but the former is less effective.
